My MotoRun 鍵盤控制版本

如果想不透過Xwindow,使用pygame.mouse勢必需要一點工夫,
shell mode下 驅動mouse定義winodws size,應該是可以的.要花點時間.
現在腦袋跳出來的想法是透過Frame Buffer.不過….應該可以WiFi遙控?
(都要IOT了,靠藍芽遙控一點都沒有Internet on thing的feeling).

使用Putty,藉由telnet login後.利用WiFi控制呢.
如可行 亦可以使用Smartphone連線操作.
以下版本是用 鍵盤上下左右按鍵 做為控制的版本 但尚未完成,不清楚telent是否能控制,擔心需要使用到Xwindow…
